Hey all,

Im new to the board and wanted to see if you all could help me out.
Im currently trying to display an image using the explode(); function.
I looked at tutorials online and tried to search the forum but im not finding
anything. A snippet of code is attatched to this can anybody tell me what im doing
wrong?

Thanks in advance
Zack

My string to be exploded was like this "http://www.anyurl.com/img.png|altTag"


<?php
    $SpecialOffers = get_post_meta($post-> ID, 'specials' , true);

    $img = explode(\"|\",$SpecialOffers);
						
            $imgUrl = $img[0];
            $imgAlt = $img[1];
							
    echo \"<a href=\"/specials\"><img src=\"$imgUrl;\" alt=\"$imgAlt;\" /></a>\";
?> 
					
                    
<div id=\"specials\">
    <?php $img; ?>
</div>

I had the code as this before and it didnt give me errors, but did not show the content.


<?php
    $SpecialOffers = get_post_meta($post-> ID, 'specials' , true);

    $img = explode(\"|\",$SpecialOffers);
						
            $imgUrl = $img[0];
            $imgAlt = $img[1];

?> 
<div id=\"specials\">
    <img src=\"<?php $imgUrl; ?>\" alt=\"<?php $imgAlt; ?>\" />
</div>

Not sure if the space in $post-> ID is causing a problem. Might be better to change it to $post->ID.

Looks like you have correctly created your $img variable, you just need to echo it to output it.

<div id=\"specials\">
    <?php echo $img; ?>
</div>

As long as the list you are trying to explode is separated with "|" and not a standard "," you should be fine :)

Found my problem, I forgot to echo out my php, Can't believe i forgot tht lol... although errors like that are usually the simplest to take care of.

Thanks again guys

This should also be useful for future reference....

echo \"<a href=\"/specials\"><img src=\"$imgUrl\" alt=\"$imgAlt\" /></a>\";

The problem with this code is that the quotes for the attributes need to have backslashes in front of them like this..

echo \"<a href=\\"/specials\\"><img src=\\"$imgUrl\\" alt=\\"$imgAlt\\" /></a>\";
